Daikin chillers achieve high seasonal energy efficiency
Published: June 2011
Daikin Europe’s EWAD~CZ range of air-cooled chillers with inverter-driven screw compressors achieve an ESEER (European seasonal energy-efficiency rating) of up to 6, with optional fan-speed regulation. Variable-speed operation makes the well suited to applications with variable loads, such as comfort cooling. Inverter technology also contributes to quieter operation and precise chiller water temperatures — as well as lower starting currents, power factor always being above 0.95, less buffer-tank capacity for the hydraulic system and increased reliability because of fewer compressor operating cycles. These chillers have cooling capacities from 635 to 1800 kW. For more information on this story, click here: June 2011, 84 Related articles:
